  • Illinois Water Resources Center Annual Technical Report FY 2017
    Illinois Water Resources Center Annual Technical Report FY 2017 Illinois Water Resources Center Annual Technical Report FY 2017 1 Introduction Illinois water resources are diverse, ranging from Lake Michigan to the Mississippi River to tile drains in agriculture fields. As a result, the Illinois Water Resources Center’s outreach and research programs cover a lot of topics, and 2017 was no different. We continued to support the implementation of the Illinois Nutrient Loss Reduction Strategy, working with federal, state, and local governments entities, nonprofits, farmers, industry members, researchers, wastewater treatment professionals, and concerned citizens to decrease the amount of nutrient pollution leaving our state. Through our Annual Small Grants program, we also supported research on green stormwater solutions, road salt contamination of groundwater, nutrient dynamics in restored wetlands, temporal patterns in nutrient uptake in riparian zones, and the ability of wetland mitigation banks to compensate for plant species lost during natural wetland impacts. While the breadth of projects is exciting, the diversity of students and faculty making use of these grants meant that first-generation college students at Northwestern University were trained in research and a new faculty member at the University of Illinois at Urbana-Champaign had an opportunity to begin building a research programs in Illinois. Grants through IWRC supported 33 undergraduate and graduate students during 2017, making this one of the most prolific years in the last decade. Introduction 1 Research Program Introduction Research Program Introduction Illinois faces a gamut of water resources challenges, and our research projects reflected that this past year, ranging from the integration of green infrastructure in cities to patterns of nitrate uptake in agricultural buffer zones.

  • Streams Campaign
    Streams Campaign Description The Illinois landscape is dissected by stream and river channels and underlain with subsurface water. Three major rivers border the State of Illinois and are responsible for much of its characteristic shape. Other major freshwater habitats include bogs, fens, glacial lakes, ponds, reservoirs, spring seeps, swamps, and reservoirs. These vast aquatic resources provide vital ecosystem services to the citizens of Illinois and critical habitat for the other species that rely upon them. The Illinois Wildlife Action Plan addresses these habitats in several Campaigns including the Lake Michigan and Coastal Area Campaign, the Streams Campaign, and the Wetlands Campaign. The Streams Campaign focuses on maintaining robust communities of native wildlife and improving the capacity of lands and waterbodies to support populations of aquatic Species in Greatest Conservation Need (SGCN) through restoration, enhancement, and protection. Portions of Illinois are included in six Fish Habitat Partnerships (http://fishhabitat.org/partnerships) and four Landscape Conservation Cooperatives (http://lccnetwork.org/find-an-lcc). Common goals for these regional efforts include the protection of healthy waters, restoration of natural flows, reconnection of fragmented stream habitats, and the improvement of water quality by reducing sediment and nutrient loading. The Streams Campaign supports these goals and strives to have local efforts in Illinois contribute to regional conservation. The Streams Campaign is organized around six basic themes that provide continuity and focus to Conservation Actions identified as priorities for effective aquatic conservation in Illinois. These themes broadly organize activities necessary to address critical stressors and evaluate the effectiveness of conservation actions on aquatic species and their habitats.

  • Site History and Environmental Monitoring Report For
    Foreword This 2009 Site History and Environmental Monitoring Report for the Sheffield Low-Level Radioactive Disposal Site was developed by the Illinois Emergency Management Agency (IEMA), Bureau of Environmental Safety (BES) to provide information to anyone interested in this closed low-level radioactive waste (LLRW) disposal site. This report provides historical background on the Sheffield LLRW site and its operation including the context of the time that it operated, design flaws, remedies, key regulatory issues, and the site’s past and current performance. IEMA published this report in an effort to communicate background information on the site, the current conditions and hopefully answer questions that residents and the general public may have about the Sheffield LLRW site. IEMA’s continuing objective at the closed Sheffield LLRW site is to ensure that the radionuclides entombed there are isolated from people and the environment, in accordance with regulatory requirements, until the radionuclides become stable through radioactive decay. Questions regarding the Sheffield LLW site or this report should be directed to: Gary McCandless, P. E. Chief, Bureau of Environmental Safety Illinois Emergency Management Agency 1035 Outer Park Drive Springfield, IL 62704 Phone: 217-785-9954 Fax: 217-524-6417 Copies of this report may be obtained from IEMA BES or by downloading it from http://www.state.il.us/iema/publications/publications.asp.
